landscape

问题 I am trying to make an app with two fragments, one containing a list of groups (called OverviewFragment) and one fragment containing the details of selected group (called DetailsFragment). I want only one fragment to be visible at a time in portrait mode and both to be visible simultaneously in landscape mode. I have two problems. First of all the transition between portrait and landscape is very unstable and leads to a variety of crashes, i.e: a blank screen, "No view found", "Error

问题 The iphone app I am developing in landscape mode is seriously chugging. I put it in portrait for comparison and it appears to run much smoother in that orientation. I am not doing what I'd think is process intensive: a map view, some buttons, some labels, and some quartz drawing, yet some basic quartz animation seriously slows down really badly. Does anyone know if landscape mode is just terribly handicapped compared to portrait, and/or if so, if there are better ways to create a landscape

问题 I'm loading basic HTML into DOMPDF. In landscape mode, all the pages after the first are overlapping. Here is my (basic) HTML which renders fine in the browser: <div id="certificates-layout-1" style="<?php echo $styles['outer-container']; ?>"> <div style="<?php echo $styles['inner-container']; ?>"> <div style="<?php echo $styles['fullname']; ?>"> <?php echo $data['fullname']; ?> </div> <div style="<?php echo $styles['fullcouncil']; ?>"> <?php echo $data['fullcouncil']; ?> </div> <div style="<

问题 I am working on an app (my first one), which is basically a TabBar app. To be more precise there are: - a login view controller - a tab bar controller (when login is done) - a landscape view controller that is used when the first itel of the TabBar is switch from Portrait to Landscape. So, when I am in the first tab, I need to be able to move to landscape view to display some other data. In my tab bar controller, I have implemented those methods: - (BOOL)shouldAutorotateToInterfaceOrientation

问题 I have a WebBrowser control in a Windows Forms Host in a WPF application. I know that in order to print it's contents, I use simply WebBrowser.Print() , however, how can I tell the printer to print the contents in landscape rather than a portrait orientation? I've been searching the Internet on this and oddly enough, it seems to be actually something that is a bit hard to do -- is this really the case? It seems odd to me that it wouldn't be easily implementable. Thanks! 回答1: INFO:

问题 I am trying to make a pin login for an app that is in landscape view. I am using Dart/flutter, and cannot figure out how to relocate the textinput keyboard.

问题 After reading many posts, I still haven't got a clue how to solve this problem... The first view of my app is a tableViewController. I override (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation and it always returns YES. If I hold my iPad upright under landscape orientation, it rotates right after I launch the app. However, if I put my iPad flat on the table, even though my homepage is in landscape orientation, it launches in protrait orientation. So
